Question

What was the daily average dollar amount of transactions in 2014 round to the nearest hundred million dollars

Answer 1

In one year, there were $2.5 trillion in credit card transactions. Since 1 year has 365 days and 1 trillion is a 1 with 12 zeros after it, the daily average is given as

`(2,500,000,000,000)/(365)`

which gives

`6849315068.4931506849315068493151`

There are 8 zeros in 1 hundread million, then by rounding this result to the nearest hundred million dollars, the answer is 6,800,000,000
